Application filed October 29, 1913. Serial No. 797.983.

T 0 all whom it may concern:

Be it known that I. JosEPH S. BARUCH, a citizen of the lfnited States. and a resident of New York city, in the county and State of New York, have invented a new and useful Improvement in Carbureters, of which the following is a specification.

My invention relates to carbureters. and one of the objects of the invention is to provide a simple, durable and efiicient carbureter.

Another object of the invention is to provide a carbureter having an internally heated chamber within the shell of the carbureter so arranged with respect tothe adjacent walls of the shell or to other walls within which the mixture flows. as to form therewith a portion of the passageway for conducting hydrocarbon fuel mixture to the engine, the passageway being of such dimensions as to insure-the proper heating of the mixture and vaporization of the hydrocarbon.

Another object of the invention is to produce a carbureter which may be cheaply constructed and which has few parts to be adjusted or tampered with by inexperienced operators.

Further objects of the invention will more fully appear from the following description of the preferred embodiment of my invention taken in connection with the accompanying drawings illustrating the same, in which- Figure 1 is a sectional elevation of the preferred embodiment of the carbureter; Fig. 2 is a horizontal sectional view of the same taken on line 22 of Fig. 1; Fig. 3 is a side View of a portion of the carbureter looking in the direction of the arrow 3 (Fig. 1) Fig. t is a bottom view of the lower portion of the carburetor looking in the direc tion of the arrow 4 (Fig. 1); and Fig. 5 is a view of a portion of the carbureter looking in the direction of arrow 5 (Fig. 1).

The main shell of the carbureter comprises a spherical portion 6 with upper and lower cylindrical extensions 7 and 8, each of less diameter than the spherical portion 6, the lower extension 8 being of considerably less diameter than the upper extension 7 and being provided with an air inlet opening 8'. The lower half of the cylindrical portion of the shell is preferably formed integrally with the lower extension 8, which in turn is connected through 'a.' horizontal connecting piece 9 with a hydrocarbon tank Y 10. and the lower extension is also provided with a hydrocarbon nozzle 11 supported by suitable webs 12. and this nozzle and the f horizontal connecting portion 9 are bored out to form a communicating passageway to the tank 10. The nozzle preferably extends i Close proximity to the outer wall of a horizontal cylinder 16 having suitable ports 17 so as to serve as a rotary throttle valve. The flange 15 has a cap 18 threaded thereon through which extends a spindle 19. the inner end of which is secured to the hub '20 of the valve cylinder 16 to rotate the same when the spindle is operated by the crank 21. The cylindrical flange 14 at the opposite end of the cylinder has an end plate 1 1 cut away to' form ports 22 for admitting auxiliary air, and the size of these openings or ports 'is regulated by a vane 23* rotatably mounted on the central or hub portion 2% of the end plate 14:. An end plate 25 of the valve cylinder 16 adjacent the ports 22 is also provided with ports 25 adapted to register with the ports :22 when the throttle valve is open to admit auxiliary air at high speeds. The point at which auxiliary air is allowed to enter during the opening of the throttle valve can be determined by the adjustment of the valve cylinder 16 on its spindle 19 by means of set screw 26.

The heating chamber 13 above referred to in this embodiment of my invention is in the form of a sphere of such diameter with respect to the diameter of the spherical part of the shell that a passageway formed between the outer wall of this chamber and the inner wall of the shell, while being of comparatively large cross-sectional area, is narrow in width, so that the hydrocarbon fuel mixture is spread out in a thin stream as it flows upwardly around the outer .Wall

of this chamber and is caused to flow in contact with the outer wall of the chamber in such manner that it is readily heated to produce the proper vaporization of the hydrocarbon. The tip of the nozzle 11 is preferably brought into close proximity to the lower flaring wall of this chamber, so that the hydrocarbon will strike this heated cliamber. .ltble openings in the flanges 28-28 of the upper and 'lower' halves of the shell, and

wall and will be dispersed uniformly over the flaring surface, which might not be the case if the gas were allowed to discharge lower down in the extension 8. 'The chamber may be heated by any suitable means, but in the preferred form of my invention, as illustrated, I prefer to heat the chamber by hot water, since in that case the hot water from a radiator attached to the machine can be used to heat the chamber. The heating chamber may be supported in any suitable manner within the inner shell, but in the present embodiment of the invention I have shown it positioned and supported within the shell by pipes 27-27 which also serve to'conduct the heating fluid through the These pipes pass through suitthse flanges are held together by suitable bolts 29, or otherwise.

'hile I have shown and described the best form of my invention now known to me, it is obvious that various changes in and modifications of-this form of the invention may be made without departing from the spirit or scope of'my invention, such, for example, as a heating chamber in the form of a cylinder with a tapering lower portion, or in the form of a double cone, but the present form of the invention has peculiar advantages and is more etiicient than other probable forms.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a carbureter, the combination with two concentric hollow spheres separated by.

a narrow space, of means for heating the inner sphere, means for delivering air and fuel radially against one side of the inner sphere, and means for discharging the heated and mixed material from the opposite side of the outer sphere; whereby all the entering material is spread in a uniform thin layer over the hot inner sphere and after heating and mixing is collected and delivered as hot carbureted air of homogeneous character.

'2. In a carbureter, the combination with an internally spherical hollow casing having on one side a relatively small radially disposed charge inlet passage and on the opposite side a corresponding outlet passage, of a concentric hollow sphere slightly smaller than, and fixed within, the casing, and means for heating the interior of said sphere.

3. In a carbureter, the combination with a casing provided with a spherical chamber having on one side an air inlet passage and on the opposite side a charge outlet passage, of a slightly smaller hollow sphere within said chamber, hot-fluid pipes passing into said chamber, communicating with the interior of said sphere and holding the latter concentric with the chamber, means within said inlet passage for delivering fuel radially against the sphere, and means for admitting a variable amount of auxiliary air to said outlet passage.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
